摘要
直接还原流程中 ,粘结失流是传统流化床应用的最大障碍·在铁矿石还原热力学计算基础上 ,在循环流化床的试验装置上进行热试验 ,通过调整影响循环流化床的条件因素 ,使循环流化床的工作状态达到最佳 ,在此基础上 ,研究和探讨循环流化床铁矿石直接还原过程的动力学条件·通过理论分析和大量实验 ,证实了循环流化床内铁矿石还原过程的控制步骤是颗粒表面化学反应 ,验证了全床还原率或平均还原率与平均反应时间的关系·
On the basis of dynamics calculation on Fe ore reduction process, thermal experiment was made on CFB settings. FCB's working conditions was optimized by adjusting cases that influence the conditions. The reaction in CFB was studied. The key steps of the reduction process in circulating fluidized bed are controlled by chemical reaction on the particle face. The relationship between the mean reduction rate and mean reaction time was tested.
